The gang knows the end is near as they prepare to depart from Spain and Morocco and head back to the States. And, boy, are they glad. Eleven weeks on the road in close quarters has left them all a little tired of each other's annoying habits. So they pack their bags and head to Fort Dix for their final mission. As Ellen says, ""This is the Big Dog. This is it."" While Steve worries about whether or not he can cut it in the military like his father, Ellen worries about which shade of green eye shadow goes best with camouflage. The mission involves them being trained as a Military Medical Unit, and if they succeed, they will receive the crest of perseverance. During their tactics training, they learn how to ""rush & roll"" and the importance of team effort. Since they hate the smell of each other at this point, teamwork is a little difficult. Steve gets to be the leader during the practice mission. Rather than lead, however, Steve chooses to go Rambo and do it on his own.
